More than 200 people joined anti-war groups Thursday for a rally and march around campus, meant to mark the five-year anniversary of the war in Iraq.

Police arrested 16 protesters who entered the Washington Avenue Army National Guard recruitment office on trespassing charges, a misdemeanor, Minneapolis Police Sgt. Jesse Garcia said. Two of the arrested were juveniles.

An Anti-War Committee news release said the protesters at the office were “disrupting its recruitment functions and refusing to leave.”

“They had taken over the second floor and hallway of the building, and had been warned a few times,” Garcia said, adding that there didn’t appear to be any property damage.

Tracy Molm, an officer for the University chapter of Students for a Democratic Society and organizer of the protest, was one of the students arrested.
